I really appreciate the advice so far guys. Makes me feel like I did a decent job researching my purchase 2 years ago.
If you have any suggestions on 2x GPUs that would last a long time on that board, feel free. Currently I use only 1.
You can probably sell the one you got for 150ish bucks and get a 6970 or a gtx 570.
Of course you can always pay the 150 and get an extra 5870 if you can find one.
Getting 2x6950 1gb would be awesome but i doubt anybody really needs this much of gpu power. TBH my single 6950 plays everything on ultra and looking at 3d mark results shows that your processor is slightly behind in score (look at average histogram charts) http://3dmark.com/3dm11/940903 http://3dmark.com/3dm11/1903564
